By nudging a thorium-229 nucleus into a higher energy state, physicists have made it possible to develop a nuclear clock that could probe the most fundamental forces in physics. However, there is still a long way to go.
Scientists think Tonga's record-breaking 2022 eruption was triggered by gas building up to a "critical point" rather than by a reaction between magma and seawater as previously assumed.

Scientists engineer the 'purest ever silicon' to build reliable qubits that can be manufactured to the size of a pinhead on a chip and power million-qubit quantum computers in the future.
Newfound rocks on Mars suggest the planet may have once sported an oxygen-rich atmosphere, making it more Earth-like and hospitable to life than previously thought.
The excavations have recovered weapons, necklaces, bracelets and worked bones.
A new study debunks previous findings that the dinosaur's intelligence was similar to that of primates, finding instead that they're about as smart as modern-day crocodiles.
The Infra-Red Calibration Balloon (S73-7) satellite had gone off the grid from radar not once but twice — once in the 1970s and then again in the 1990s. After 25 years missing in orbit, it has finally been rediscovered.
